Hi. I have a Galaxy S6 edge. I have recently dropped it in water but proceeded to get it out fairly quick. I dried the phone real good and the case it was in. At that time I could not slide my screen. I could see it but not do anything with it. I put it into rice overnight and all seemed fine. I was able to slide the screen, use apps, and all was good. I actually used the phone for two more days after. Then after using it all day, it decided to go out after work. The screen went black however I could still hear volume sounds, and I could still feel vibrations turning volume down. I plugged it up to see if it would charge and the charge screen did not come up. But I did get notification lights. This is about all it does, green light that stays on or red light that stays on. Once you touch a button it won’t do anything and the lights go off.
I’m going to upgrade the phone but for now I have a go phone. I’m just wanting to find out if I can get the stuff off of the black one. Pictures, Music, anything. Please let me now if this is somehow possible without costing me an arm and a leg to do it. — Juliewilliams2011
Solution: Hi Juliewilliams2011. Serious problems in Some cases of water damaged phones don’t usually surface after some time, when corrosion sets in, or when moisture inside has shorted some components. This may be the case why you were able to still use the device days after it got wet. You should have used the time to immediately send the device to a service center so it can opened, dismantled, cleaned, and dried. Together, these things constitute the “first aid” procedure to prevent permanent damage to the hardware. Because the battery has been integrated to the logic board, there’s a need to dismantle it from the board. Leaving the battery connected to a wet logic board is one of the surest way to kill a hardware (charging a wet phone is another one). Having left the battery on and charging the device a few times after the incident must have damaged the phone irreversibly at this time. It’s now safe to assume that one of the damages must be the screen.
Unfortunately, there’s no way you’ll be able to recover anything from your phone is the touchscreen is gone. The phone’s touchscreen is the only way for you to send a command to the operating system to allow a second device like a computer to unlock itself and allow access to the internal storage device. Without the touchscreen, the phone is basically locked out, inaccessible. That said, if you think the contents you want to recover are worth over a few hundred dollars, we say you go ahead with a screen replacement.
Last night, my phone’s screen kept blacking out and even though the phone was charging, the screen would not show anything. Came back to it an hour later and it was working as normal again. But the phone kept repeating the same behavior a few times. Then when I let it charge over night, the phone was really hot and the battery charge did not actually go up. I was not able to send any text messages, the clock did not change, and the battery percentage did not change until the phone ran out of battery. — Walter
Solution: Hi Walter. Like you, we have no idea what may have happened on your device, especially that you don’t provide any relevant history as to why it’s acting this way right now. Try doing a factory reset and start from there. Resetting your phone is the only way to find out if the issue is software- or hardware-related. Factory reset basically reverts all software settings to their defaults, effectively removing bugs that may have developed over time. After the reset, be sure to observe how the phone works for 24 hours without installing any app or update. If the problems remain, you have a hardware problem at hand. In that case, you want to send the phone in so it can be repaired or replaced.
Below are the steps on how to factory reset your S6:
- Create a backup of your important files (if possible at this time).
- Turn off your Samsung Galaxy S6 Edge.
- Press and hold the Volume Up, Home and Power keys together.
- When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
- Wait until the Android Recovery Screen appears after about 30 seconds.
- Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
- Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
- After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.
My Samsung Galaxy S6 (SM-G920FD) hanged after the firmware update. I’ve tried everything but even the keys do not respond until the last percentage of the battery. I’ve tried to charge it but only the lightning bolt appears. And after 15 I tried to turn back on but nothing happens. I also try all those troubleshooting guides. Yes, It turned on but it stock on logo, (The Samsung s6 Powered by Android). I really want this to fix since it’s my auntie’s gift. I hope you’ll find the solution. — Orland
Solution: Hi Orland. The best thing that you can do in this situation is to try if you can boot the phone normally after wiping the cache partition or doing a factory reset. Both of these procedures can be done by booting the phone to recovery mode. If you won’t be able to restart the phone to recovery mode, you can the other two alternate modes namely Odin and safe mode. Below are the exact steps on how to do these procedures using hardware button combinations. We also include the follow up troubleshooting that you can do for each one.
Boot in Recovery mode:
- Charge the phone for at least 30 minutes.
- Press and then hold the Home and Volume UP keys, then press and hold the Power key.
- When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
- When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
- Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
- You can either wipe the cache partition or do a factory reset when in this mode.
Boot in Download Mode:
- Charge the phone for at least 30 minutes.
- Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
- When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
- Wait until the Download screen appears.
- If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
- Use Google to look for a guide on how to do it.
Boot in safe mode:
- Charge the phone for at least 30 minutes.
- Press and hold the Power button.
- Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
- Continue holding the button until the phone finishes rebooting.
- Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
- The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.
Remember, if the phone remains unresponsive or won’t boot to any of the alternate boot modes at all, send it in for repair or replacement.
After having my Samsung Galaxy S6 edge for about a year, a horizontal green light/line is appearing. It was periodically, now it seems to be there permanently. Sometimes when pressing the top of screen (just beneath Samsung logo) it’ll disappear or cause multiple green lines. Does not appear on any pictures I’ve taken though. Not certain of android version. There was a recent software upgrade and afterwards it still appeared. Do you know of any DIY fix to correct this issue. Please advise. Thanks you. — Santonjalane
Solution: Hi Santonjalane. Try to boot the phone to any of the alternate boot modes above (Recovery Mode, Odin Mode, or Safe Mode) and see if you screen continues to show the green line. If it does, that’s a hardware problem, meaning that the LCD may have been damaged. This can’t be fixed by a software tweak obviously so you need to have the phone repaired. The screen assembly is composed of three major components — LCD, digitizer, and flex cable. We think that the LCD is damaged so you can either have this particular component only replaced, or the entire screen assembly. Either way, we won’t recommend that you do the repair yourself unless you are confident of your electronics knowledge and have the tools to do it. Screen repairs can lead to more problems if not done properly; we don’t want you to permanently brick the device.
We don’t provide guides how to do hardware repair so if you think you can do the repair yourself, try to look for a guide online. iFixit is a good site to begin hunting for good S6 screen replacement guides.
Since I updated my S6 edge to Marshmallow, it doesn’t pick up my SIM card. When I try to turn on mobile data, it says insert SIM card even though it’s already inserted. when I call or text it says no SIM card, insert SIM card. The SIM card works in other mobile phones though. When I updated at first there was an error of com.android.phone so I factory reset my phone and that error was fixed. But since the reset the SIM card problems remains. — Hamza
Solution: Hi Hamza. How did you update your device? Did you download the update by air (OTA), or by manual flashing? If it’s via OTA, contact your carrier and let them know about the problem. Hopefully they’re already aware of it and will soon release a patch for it.
If you tried to update your device via manual flashing, consider flashing the stock firmware to fix the issue. We can’t provide ROM-specific fix if this is a problem caused by poor firmware coding. If you really want to get to the bottom of the problem and want to continue using the custom firmware, contact the developer for a fix.
My phone works fine until I press the speakerphone. I can hear the other person but they cannot hear me. People hear me just fine when I don’t have it on speaker. I don’t know how to “reset” that. The microphone works, the speaker works… unless I put on speakerphone and then they can’t hear me. I took it to the Verizon store and they witnessed it, but didn’t do anything about it. Told me to call Assurion. Help. Thank you. — Jody
Solution: Hi Jody. Must be a software glitch. Have you tried doing a factory reset yet? If not, here’s how to do it:
- Create a backup of your important files.
- From the Home screen, tap the Apps icon.
- Find and tap the Settings icon.
- Under the ‘Personal’ section, find and tap Backup and reset.
- Tap Factory data reset.
- Touch Reset device to proceed with the reset.
- Depending on the security lock you used, enter the PIN or password.
- Tap Continue.
- Touch Delete all to confirm your action.
If the problem remains after a factory reset, consider getting a phone replacement.
Sir i recently purchased a used cell, Samsung Galaxy S6 edge. When i want to update it gives a warning message that your device is modified in an unauthorized way. When i searched about it i came to know that when the device’s status is costumed it will happen but here my device’s status is still official and it’s not updating stil using version 5.0.2. kindly help me out. — Zahid
Solution: Hi Zahid. If you’re trying to download the update by air, that is by receiving the files from your carrier, the reason is probably because the phone does not come from them in the first place. Keep in mind that firmware updates from a carrier are only compatible with their own devices. For example, an AT&T update can only be installed on an AT&T phone and not on a T-Mobile’s.
If you happen to have a phone from the same carrier but an OTA update keeps giving you the warning message, it’s possible that the phone may be rooted although it’s still running the official or stock firmware. To check if your phone is rooted or not, head over to Google Play Store and install Root Checker app.
Yesterday my phone did a full factory reset on its own. I’ve been able to recover most items however I cannot seem to separate the sounds between notifications and email. I set the notification sound first, then went to email notification and set a different sound. Both email and notification play the notification sound. I tried changing sounds, but each time the email would play the notification sound. — Joe
Solution: Hi Joe. First of all, we say that something’s not working right on your phone. Factory resetting on its own is not good and suggests that the system may be compromised, or that there’s an unknown software glitch causing it. Secondly, you should be able to use different sound for both email and standard notification. That this is not happening is a clear indication of a problem. To know if both issues are related or caused by the same thing is impossible provided we have no previous knowledge or history of your device. As far as we know, these issues have not been reported in Galaxy S6 running official firmware. If you happen to modify the firmware or installed unofficial software on your device, consider reverting to official software.
For the notification sound issue, you can use other third party apps like Zedge for a remedy. Zedge can be installed for free from the Play Store.
Not sure if it’s because I disabled some apps. I thought they were safe to disable when I did the latest system update on my S6, it froze while restarting. The Sprint splash screen comes on with sound and animation, then it freezes. None of the buttons work and the phone gets hot.
I tried clearing data/factory reboot, didn’t fix it. I tried clearing cache, didn’t fix it. I tried removing micro and SIM cards, didn’t fix it. I tried draining power with the power button, didn’t fix it. I tried going to download screen and restarting, didn’t fix it. I’ve done everything I’ve read about/watched except downloading new firmware with Odin. Should I do that? One video warned not to. Please help if you can! Thanks. — Teri
Solution: Hi Teri. If the hardware buttons are not working, there’s really very little to nothing that you can do in terms of software troubleshooting here. Not even flashing via Odin mode. Refer to the steps we provide for Orland above and see if you can do certain button combinations to boot the phone back. Your best bet is to hope that you can boot it to recovery mode so you can wipe the cache partition or do a master reset. Safe mode is much better and may work if the problem is being caused by a third party app. If your phone restarts to safe mode fine, you should uninstall third party apps until the problem is fixed.
Manual flashing can only be done after booting the device to download mode so you should try that as a last resort. Flashing is a risky procedure and should only be done by advanced Android users. If this is your first to hear about it, or you’re not familiar on how to do it, make sure to do some research on how to do it first. Flashing is phone model specific so be sure to use the guide on how to do it for your own device. We suggest that you try to flash the bootloader first to see if that will work. If nothing will change after flashing the bootloader, that’s the time that you flash the stock firmware.
As a reference, here are the steps on how to flash the bootloader. Remember, these are general steps only and there may be a more specific set of steps on how to do this on your device.
- Look for the correct firmware for your phone model and download it. Make sure that select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
- Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
- Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
- Proceed with the rest of the flashing procedure using the Odin program.
- In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
- Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
If your phone won’t start to any of the three hardware button combinations, you should consider sending the phone in to Samsung for repair or replacement.
Hi. I have issues with my Galaxy S6 edge plus. Fast charging stopped working after the last update by Samsung. I have changed USB cables and adapters and checked if it’s on from the phone settings but still not working. I even replaced the USB port and after that update, my phone is not recognized by my laptop. I want to downgrade from Android 6 to 5. Please help me to fix these issues. Thanks. — Mido
Solution: Hi Mido. There’s only so much that you can do about this issue. Fast charging feature both have a software and hardware components. If changing the charging port did not fix the problem, try flashing the software back to its original version, that is, Android Lollipop or Marshmallow (depending on what firmware version it shipped with) when you unboxed it. If that won’t work still, there may be an unknown hardware issue that causes the phone to glitch. Knowing where the point of failure lies is very difficult, if not impossible, for us. We don’t think Samsung technicians can do it for you either as it involves a lot of time to run a series of diagnostics. The best thing that you can do in this case is to see if you can get a replacement.
